Product Summary

HONG YE SILICONE’s Liquid Foamed Silicone is a flame-retardant 2-component addition curing silicone, featuring excellent flame retardancy (UL94 V-0 certified, no dripping, self-extinguishing time ≤3s), fireproof, suitable for fire-retardant equipment, electrical enclosures and flame-retardant scenarios. It has fine uniform closed-cell pores, -65℃-200℃ temperature resistance, 1:1 easy operation, passed SGS flame retardant test, compatible with high-precision mold silicone and electronic potting compound, serving B2B buyers in fire-retardant, electrical and safety industries.

Product Overview

HONG YE SILICONE’s Liquid Foamed Silicone (foaming silicone rubber, silicone foam) is a flame-retardant UL94 V-0 core product, specially developed for fire-retardant equipment, electrical enclosures and flame-retardant scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with flame retardants and fireproof modifiers, featuring UL94 V-0 certification, no dripping, self-extinguishing, fine uniform closed-cell structure, good elasticity and flame-retardant stability. It achieves UL94 V-0 flame retardancy, self-extinguishing time ≤3s, no dripping, effectively inhibiting flame spread, solving the problem of traditional foaming materials’ flammability in fire-retardant scenarios. Compatible with most of our fire-retardant and electrical products, it is ideal for flame-retardant components, fireproof buffers and flame-retardant scenarios.

Product Features & Advantages

1. Strict Flame Retardant Certification: UL94 V-0 certified, self-extinguishing time ≤3s, no dripping, solving the problem of traditional foaming materials’ flammability in fire-retardant scenarios.

2. Effective Fireproof Performance: Flame-retardant efficiency ≥95%, no smoke generation, effectively inhibiting flame spread, protecting equipment and personnel safety in fire scenarios.

3. Flame Retardant & Elasticity Balance: While maintaining UL94 V-0 flame retardancy, it retains good elasticity and structural stability, no brittle fracture, balancing flame retardancy and usability.

4. Compatibility with Fire-Retardant Products: Compatible with HONG YE SILICONE’s high-precision mold silicone and electronic potting compound, forming a complete flame-retardant solution, enabling one-stop procurement.

5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into flame-retardant components, no professional flame-retardant operation skills required, improving production efficiency.

How to Use

1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting flame retardancy and fireproof performance).

2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform flame retardancy and closed-cell structure, no flame penetration).

3. Pour the mixture into flame-retardant component mold (paired with high-precision mold silicone), foam and cure at room temperature or by heating (heating helps enhance flame-retardant stability).

4. After full curing, test flame retardancy (UL94 V-0, self-extinguishing time ≤3s) to confirm qualification, then use in flame-retardant and fireproof scenarios.

Application Scenarios

Focus on flame-retardant scenarios: Fire-retardant equipment buffers (paired with high-precision mold silicone), electrical enclosure flame-retardant parts (paired with electronic potting compound), flame-retardant packaging (paired with liquid tank silicone), fire-retardant machinery components (paired with industrial mold silicone rubber), and flame-retardant robot parts (paired with robot silicone). It helps fire-retardant and electrical industry buyers inhibit flame spread and ensure safety.

Certifications and Compliance

Passed SGS eco-toxicity certification, RoHS compliant, UL94 V-0 certification, SGS flame retardant test certification, excellent flame retardancy and fireproof performance, meeting the flame-retardant procurement requirements of B2B buyers in fire-retardant, electrical and safety industries, facilitating export to global markets.

Customization Options

Customizable flame retardant grade (UL94 V-0+ for high-demand scenarios), self-extinguishing time (≤2s for high-demand scenarios), foaming ratio and hardness, adapting to different flame-retardant requirements, helping buyers optimize fireproof effect.

Production Process

Flame-retardant-oriented production process: High-purity flame-retardant silicone raw materials → formula optimization (add flame retardants and fireproof modifiers) → precision mixing → flame retardant test (UL94 V-0) → fireproof test → standardized curing → flame-retardant stability inspection → packaging. Strict flame retardant testing ensures product UL94 V-0 flame retardancy and fireproof performance.
